This adds a new service that registers metrics on boot. It also removes metrics registration from the other services boot sequences. This service is deployed but inaccessible and purely exists to register metrics.
**Upgrade notice!** This release introduces a new service which must be tagged and applied. You can run `terraform taint null_resource.build` before running Terraform to build this service. This service is responsible for metric registration and does not receive user traffic.
